Application during pregnancy and lactation

Contraindicated during pregnancy and breastfeeding.

Application for violations of liver function

Patients with impaired liver function do not require a special selection of doses, since levofloxacin is metabolized in the liver only to an extremely insignificant extent.

Application for impaired renal function

Patients with impaired renal function require correction of the dosage regimen, depending on the CC value. Patients after hemodialysis do not require additional doses.

Application in children

Levofloxacin cannot be used to treat children and adolescents (under 18 years of age) due to the likelihood of damage to the articular cartilage.

Use in elderly patients

When treating elderly patients, it should be borne in mind that patients in this group often suffer from impaired renal function.

special instructions

Hospital infections caused by Pseudomonas aeruginosa may require combination treatment. The prevalence of acquired resistance in plated strains of microorganisms can vary depending on the geographic region and over time. Therefore, country-specific information on levofloxacin resistance is required.

For the treatment of severe infections or in case of ineffectiveness of treatment, a microbiological diagnosis should be established with the isolation of the pathogen and determination of its sensitivity to levofloxacin. There is a high likelihood that methicillin-resistant Staphylococcus aureus will be resistant to fluoroquinolones, including levofloxacin. Therefore, levofloxacin is not recommended for the treatment of established or suspected infections caused by methicillin-resistant Staphylococcus aureus, if laboratory tests have not confirmed the susceptibility of this microorganism to levofloxacin. Like other quinolones, levofloxacin should be used with great caution in patients with a predisposition to seizures. Such patients include patients with previous lesions of the central nervous system, such as stroke, severe traumatic brain injury; the patients,concomitantly taking drugs that lower the seizure threshold of the brain, such as fenbufen and other similar NSAIDs or other drugs that lower the seizure threshold, such as theophylline Diarrhea that develops during or after treatment with levofloxacin, especially severe diarrhea, persistent and / or with blood may be a symptom of Clostridium difficile pseudomembranous colitis. In case of suspicion of the development of pseudomembranous colitis, treatment with levofloxacin should be stopped immediately and specific antibiotic therapy (vancomycin, teicoplanin or oral metronidazole) should be started immediately.such as theophylline Diarrhea that develops during or after treatment with levofloxacin, especially severe, persistent and / or bloody, may be a symptom of pseudomembranous colitis caused by Clostridium difficile. In case of suspicion of the development of pseudomembranous colitis, treatment with levofloxacin should be stopped immediately and specific antibiotic therapy (vancomycin, teicoplanin or oral metronidazole) should be started immediately.such as theophylline Diarrhea that develops during or after treatment with levofloxacin, especially severe, persistent and / or bloody, may be a symptom of pseudomembranous colitis caused by Clostridium difficile. In case of suspicion of the development of pseudomembranous colitis, treatment with levofloxacin should be stopped immediately and specific antibiotic therapy (vancomycin, teicoplanin or oral metronidazole) should be started immediately.

Drugs that inhibit intestinal motility are contraindicated.

Tendonitis is rarely observed with quinolones, including levofloxacin, and can sometimes rupture tendons, including the Achilles tendon. This side effect can develop within 48 hours after starting treatment and can be bilateral.

Elderly patients are more prone to develop tendonitis; in patients taking fluoroquinolones, the risk of tendon rupture may increase with the simultaneous use of corticosteroids. In addition, patients after transplantation have an increased risk of tendinitis, so it is recommended to be careful when prescribing fluoroquinolones in this category of patients.

If you suspect the development of tendonitis, you should immediately stop treatment with levofloxacin and begin appropriate treatment of the affected tendon, for example, ensuring it is sufficiently immobilized. Levofloxacin can cause serious, potentially fatal, hypersensitivity reactions (angioedema, anaphylactic shock), even with initial doses. In such cases, you should immediately stop using levofloxacin and consult a doctor.

With the use of levofloxacin, cases of severe bullous skin reactions such as Stevens-Johnson syndrome or toxic epidermal necrolysis have been observed.

In case of development of any reactions from the skin or mucous membranes, the patient should immediately consult a doctor and not continue treatment until his consultation. Cases of liver necrosis, including the development of fatal liver failure, have been reported with the use of levofloxacin, mainly in patients with severe underlying diseases, such as sepsis. Patients should be warned about the need to discontinue treatment and seek urgent medical attention if signs and symptoms of liver damage appear, such as anorexia, jaundice, dark urine, pruritus and abdominal pain. Since levofloxacin is excreted mainly through the kidneys, in patients with impaired renal function, mandatory monitoring of renal function is required, as well as correction of the dosage regimen.

When treating elderly patients, it should be borne in mind that renal dysfunction is often observed in patients of this group. Although photosensitization develops very rarely when using levofloxacin, to prevent its development, patients are not recommended during treatment and within 48 hours after the end of treatment with levofloxacin to be exposed to strong solar or artificial ultraviolet radiation (for example, to visit a solarium). As with the use of other antibiotics, the use of levofloxacin, especially for a long time, can lead to increased reproduction of microorganisms (bacteria and fungi) insensitive to it, which can cause changes in the microflora that is normally present in humans. As a result, superinfection may develop.Therefore, during treatment, it is imperative to re-evaluate the patient's condition, and, if superinfection develops during treatment, appropriate measures should be taken. Very rare cases of prolongation of the QT interval have been reported in patients taking fluoroquinolones, including levofloxacin.

When using fluoroquinolones, including levofloxacin, caution should be exercised in patients with known risk factors for prolongation of the QT interval: in patients with uncorrected electrolyte disturbances (with hypokalemia, hypomagnesemia); with congenital lengthening of the QT interval; with heart disease (heart failure, myocardial infarction, bradycardia); with the simultaneous use of drugs that can lengthen the QT interval, such as class IA and III antiarrhythmics, tricyclic antidepressants, macrolides, antipsychotics.

ѕациенты пожилого возраста и пациенты женского пола могут быть более чувствительными к препаратам, удлин¤ющим интервал QT. ѕоэтому следует с осторожностью примен¤ть у этой категории больных фторхинолоны, включа¤ левофлоксацин. ” пациентов с латентным или манифестированным дефицитом глюкозо-6-фосфатдегидрогеназы имеетс¤ предрасположенность к развитию гемолитических реакций при лечении хинолонами, что следует принимать во внимание при лечении левофлоксацином.  ак и при применении других хинолонов, при применении левофлоксацина наблюдались случаи развити¤ гипергликемии и гипогликемии. Ќа фоне терапии левофлоксацином дисгликеми¤ чаще возникала у пациентов пожилого возраста и пациентов с сахарным диабетом, получающих сопутствующую терапию пероральными гипогликемическими препаратами (например, глибенкломидом) или инсулином. ѕри применении левофлоксацина у таких пациентов возрастает риск развити¤ гипогликемии, вплоть до гипогликемической комы. Ќеобходимо информировать пациентов о симптомах гипогликемии (спутанность сознани¤, головокружение, 'волчий' аппетит, головна¤ боль, нервозность, ощущение сердцебиени¤ или учащение пульса, бледность кожных покровов, испарина, дрожь, слабость).

If the patient develops hypoglycemia, it is necessary to immediately discontinue treatment with levofloxacin and initiate appropriate therapy. In these cases, it is recommended to switch to therapy with an antibiotic other than fluoroquinolones, if possible. When treating with levofloxacin in elderly patients, in patients with diabetes mellitus, careful monitoring of the blood glucose concentration is recommended. In patients taking fluoroquinolones, including levofloxacin, cases of sensory and sensory-motor peripheral neuropathy have been reported, the onset of which can be rapid.

If the patient develops symptoms of neuropathy, the use of levofloxacin should be discontinued. This minimizes the possible risk of developing irreversible changes. Fluoroquinolones, including levofloxacin, are characterized by neuromuscular conduction blocking activity and may increase muscle weakness in patients with pseudoparalytic myasthenia gravis. Adverse reactions, including pulmonary insufficiency requiring mechanical ventilation, and death were observed, which were associated with the use of fluoroquinolones in patients with pseudoparalytic myasthenia gravis.

The use of levofloxacin in a patient with an established diagnosis of pseudoparalytic myasthenia gravis is not recommended.

Application for airborne anthrax infection is based on data on the sensitivity of Bacillus anthracis to it, obtained in in vitro studies and in experimental studies conducted on animals, as well as on limited data on the use of levofloxacin in humans. Treating physicians should refer to national and / or international documents that reflect a common consensus on anthrax management. Psychotic reactions, including suicidal thoughts / attempts, have been reported in patients taking fluoroquinolones, including levofloxacin, sometimes after taking a single dose. If any side effects from the central nervous system develop, including mental disorders, treatment with levofloxacin should be stopped immediately and appropriate therapy should be prescribed.In these cases, it is recommended to switch to therapy with an antibiotic other than fluoroquinolones, if possible.

Care should be taken to prescribe the drug to patients with psychosis or patients with a history of mental illness. In patients taking levofloxacin, the determination of opiates in urine can lead to false positive results, which should be confirmed by more specific methods. Levofloxacin can inhibit the growth of Mycobacterium tuberculosis, which can lead to further false negative results of the bacteriological diagnosis of tuberculosis. When conducting intravenous infusion, the recommended duration of administration should be strictly adhered to. Experience with levofloxacin shows that an increased heart rate and a transient decrease in blood pressure can be observed during infusion. In rare cases, vascular collapse may develop. If during the intravenous infusion of levofloxacin there is a pronounced decrease in blood pressure,then its introduction is stopped immediately.

Influence on the ability to drive vehicles and mechanisms

During the period of treatment, it is necessary to refrain from engaging in potentially hazardous activities that require increased concentration of attention and speed of psychomotor reactions.

Drug interactions

There are reports of a pronounced decrease in the threshold of convulsive readiness with the simultaneous use of quinolones and substances that can, in turn, lower the cerebral threshold of convulsive readiness. This also applies to the simultaneous use of quinolones and theophylline. The effect of levofloxacin is significantly weakened when used simultaneously with sucralfate. The same thing happens with the simultaneous use of magnesium- or aluminum-containing antacids, as well as iron salts. Levofloxacin should be taken at least 2 hours before or 2 hours after taking these drugs. With the simultaneous use of vitamin K antagonists, it is necessary to control the blood coagulation system. Excretion (renal clearance) of levofloxacin is slightly slowed down by cimetidine and probenecid. It should be noted,that this interaction has practically no clinical significance. However, with the simultaneous use of drugs such as probenecid and cimetidine, which block a certain route of excretion (tubular secretion), treatment with levofloxacin should be carried out with caution. This applies primarily to patients with limited renal function. Levofloxacin slightly increases the T1 / 2 of cyclosporin. Taking GCS increases the risk of tendon rupture.Taking GCS increases the risk of tendon rupture.Taking GCS increases the risk of tendon rupture.
